Document No. 570-134 Installation Instructions October 26, 2016 CAUTION DO Wiring – Each DO provides a Normally Open (NO) terminal and a Common (C) terminal. To reduce noise and the potential for ground loops, both connections of a 24 Vac load must be wired directly to the DO terminal on the controller board. Raccordement des sorties numériques (DO) – chaque DO se compose d’une borne normalement ouverte (NO) et d’une borne commune (C).

Document No. 570-134 Installation Instructions October 26, 2016 NOTE: If the voltage/current switch is set to current and a 4 to 20 mA sensor is connected to an AI, then special wiring requirements must be followed. NOTE: When wiring any actuator that uses a 0 to 10V control signal and ties AC neutral to DC common, an additional wire must connect the actuator AC neutral to the DC common of the PTEC/TEC AO being used to control the actuator.
